collaborations, in recognition of their combined work on the gluon as the "definite existence (of the gluon) emerged gradually from the results of the TASSO collaboration and the other experiments working at PETRA, JADE, MARK J and PLUTO". TASSO took data from 1978 to 1986 and discovered the gluon in 1979.
